Abstract: The two title mononuclear compounds are four-coordinate bis[N-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazolidin-2-ylidene)glycinato]copper(II) dimethylformamide disolvate, [Cu(C₁₇H₁₄N₃O₃)₂]·2C₃H₇NO, (I), and five-coordinate aquabis[N-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazolidin-2-ylidene)glycinato]copper(II) dimethylformamide disolvate, [Cu(C₁₇H₁₄N₃O₃)₂(H₂O)]·2C₃H₇NO, (II). In (I), the Cu^II ion lies on an inversion centre with one-half of the complex molecule in the asymmetric unit, while in (II) there are two independent ligand molecules in the asymmetric unit, with the Cu^II ion and coordinated water molecule located on a general position. In both crystal structures, the complex molecules assemble in ribbons via N-HO hydrogen-bond networks.

Formula: [Cu(C₁₇H₁₄N₃O₃)₂]·2C₃H₇NO and [Cu(C₁₇H₁₄N₃O₃)₂(H₂O)]·2C₃H₇NO
